在我的代码底部，我不知道它不起作用
holder.newsItem.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if(isOnline()) {
Intent i = new Intent();
i.setClass(getContext(), NewsDetali.class);
i.putExtra("id", ArrayListNews.get(position).getId());
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
//error this line
((Activity) context).overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);
} else {
Toast.makeText(getContext(), "Отсутствует подключение к интернету", Toast.LENGTH_LONG).show();
}
}
});
更新:
所有代码
public class NewsAdapter extends ArrayAdapter<NewsObject>{
ArrayList<NewsObject> ArrayListNews;
int Resourse;
Context context;
LayoutInflater vi;
private ImageLoader imageLoader;
final View imageLayout;
//final ProgressBar spinner;
public NewsAdapter(Context context, int resource, ArrayList<NewsObject> objects, ImageLoader imageLoader) {
super(context, resource, objects);
ArrayListNews = objects;
Resourse = resource;
this.context = context;
vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.imageLoader = imageLoader;
imageLayout = vi.inflate(R.layout.item_pager_image, null);
//spinner = (ProgressBar) imageLayout.findViewById(R.id.loading);
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if(convertView == null) {
convertView = vi.inflate(Resourse, null);
holder = new ViewHolder();
Typeface face=Typeface.createFromAsset(context.getAssets(), "font/AvenirNext-Regular.ttf");
holder.imageNews = (ImageView) convertView.findViewById(R.id.imageNews);
holder.nameNews = (TextView) convertView.findViewById(R.id.nameNews);
holder.dateNews = (TextView) convertView.findViewById(R.id.dateNews);
holder.newsItem = (RelativeLayout) convertView.findViewById(R.id.newsItemAdapter);
holder.loadImg = (PlayGifView) convertView.findViewById(R.id.loading_bg);
holder.nameNews.setTypeface(face);
holder.dateNews.setTypeface(face);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
imageLoader.displayImage(ArrayListNews.get(position).getImageLink(), holder.imageNews, null, new ImageLoadingListener() {
@Override
public void onLoadingStarted(String arg0, View arg1) {
}
@Override
public void onLoadingFailed(String arg0, View arg1, FailReason arg2) {
}
@Override
public void onLoadingComplete(String arg0, View arg1, Bitmap arg2) {
int color = Color.parseColor("#4D000000"); //The color u want
holder.imageNews.setColorFilter(color);
holder.nameNews.setText(ArrayListNews.get(position).getName());
holder.dateNews.setText(ArrayListNews.get(position).getDate());
}
@Override
public void onLoadingCancelled(String arg0, View arg1) {
Log.e("Script", "OnLoadeingStarted");
}
}, new ImageLoadingProgressListener() {
@Override
public void onProgressUpdate(String uri, View view, int current, int total) {
Log.e("Script", "OnProgressUpdate" + uri + " " + total);
}
});
holder.newsItem.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(getContext(), NewsDetali.class);
i.putExtra("id", ArrayListNews.get(position).getId());
i.putExtra("title", ArrayListNews.get(position).getName());
i.putExtra("image", ArrayListNews.get(position).getImageLink());
i.putExtra("description", ArrayListNews.get(position).getDescription());
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
//danger line!!! Error this
overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);
}
});
return convertView;
}
static class ViewHolder {
public ImageView imageNews;
public TextView nameNews;
public TextView dateNews;
public RelativeLayout newsItem;
public PlayGifView loadImg;
}
}
最佳答案
像这样的代码改变
Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
Bundle b = new Bundle();
b.putInt("key", 1); //Your id
intent.putExtras(b); //Put your id to your next Intent
startActivity(intent);
getActivity().overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);
然后在 newActivity 中接收
Bundle b = getIntent().getExtras();
int value = b.getInt("key");
